Prolactin - Tren/Deca

[Sworder]

The effect of trenbolone on acetate growth, blood hormones and metabolites, and nitrogen balance of beef heifers
http://journals.cambridge.org/action...ne&aid=7365892

Abstract:

Four animals from a group of eight Hereford × Friesian heifers weighing approximately 365 kg were implanted with 300 mg trenbolone acetate at the beginning of a 60-day trial period. Treated heifers grew more quickly (P<0·05) and converted food to liveweight gain more efficiently (P < 0·01) than untreated cdntrols. They had lower overall concentrations for serum albumin and plasma urea (P<0·01), the differences being maintained throughout the diurnal periods studied. No significant differences were recorded in the mean values for serum total protein, plasma glucose or free fatty acids. Similarly, the absence of significant differences in the mean values for serum growth hormone, insulin and prolactin suggested that these hormones did not mediate the response to trenbolone acetate. Implanted heifers had a significantly greater retention of nitrogen (P<0·01) which was mainly due to a reduction in the excretory products associated with total urinary nitrogen.

Beef heifers...

I think you need to give google a rest.

You aren't going to find a lot of studies on trenbolone in humans!! This is how science is done, experiment on animals and extrapolate information to humans. But no matter how much I Google I can't seem to find anything that supports trenbolone increases PROLACTIN. It is heiferpoop, broscience, a myth!!

Edit: Maybe that is too harsh. If I put it like this, it is not supported by science. Also, Progestins are NOT Progesterone!! They aren't the same compound and they won't signal the brain to start producing prolactin.

I'm pretty sure I know what "science is" Sworder.

I've backed every dam claim I have ever made with a reference or multiple references.

If you don't believe that, please go through my threads/articles/posts and tell me where I haven't.

You wont find much on 19-Nor's and Prolactin, its a question thats been raised for years and years with no proof that progestins raise PRL directly.

I am sorry if I offended you, but you seemed to disregard the study just because it is not conducted on humans. I think this is a interesting subject to discuss, and I feel comfortable stating that there isn't enough scientific evidence to suggest that Trenbolone increases prolactin. Do you disagree? I honestly don't know where or how this rumor came to be. All I do know is that:
1. There is no scientific evidence to support it.
2. I have never lactated from trenbolone use even at 600mg+/week
3. I have never heard of anybody lactating or having elevated prolactin levels with trenbolone being the cause. I have asked a lot of people personally about this through PMs.

Exactly!!! So why take cabergoline or other DA? It's a waste of money.

The key here is to keep it in normal ranges when "on cycle", not high off the charts and not too low. To low and we can experience a host of other side effects, from loss of labido, energy, joint problems, CNS function, anxiety and erectile dysfunction.

If you call me out like that I am gonna have to respond, not going to scour your threads but I remember reading that one. If you would please show me a study showing the correlation between low e2 and libido(with testosterone levels being in the 50th percentile) I would stand corrected. I have searched far and wide for that correlation but have only found one and that one was lacking in some data. I am not stating I don't believe it, just asking for a reference to the data as you claim to always have one or two. I usually try to refrain from absolute terms such as never or always.

Edit: If you do please send a link in a PM and I will update this post showing the relation. Would like to refrain from soiling the thread with too much off-topic discussions.

Sure.

Run Letrozole and 5mg/ED and tell me what happens to your labido clever clogs.

Are you aware that estrogen is probably the hormone that keeps sex drive up in castrated men? Estrogen receptors are present in tissues involved in sexual behavior including several brain centers and pelvic floor muscles as well.

I apologize for the confusion I was asking for a reference not a proposal on how to conduct a "broscience" experiment. Controlled studies, not personal anecdotes is what counts. I am aware of estrogen's importance and have my own theories on the subject. I will update my first post if you can send me a reference otherwise I do not wish to further the discussion with personal theories. I would appreciate if you could comment on the prolactin posts so we stay on-topic

Maybe you could be the human experiment! Take Tren and a HRT test dose and small amount of AI and monitor prolactin. Then your next cycle take same amount of Tren and higher test dose with no AI and see what happens.

The independent variable is the estrogen(produced by the testosterone and managed by AI).. If you would test for the trenbolone to be the deciding factor then that would be the independent variable.
